Another one. Find the gradients of the lines A and B.

Step-by-step explanation:

Gradient of a line is the same as slope of the line. Slope is defined as the ratio of the rate of change in the y(vertical) axis to the rate of change in the x(horizontal) axis.

Slope = (y2 - y1)/(x2 - x1)

Slope is denoted by m. Therefore,

For line A,

y1 = - 1

y2 = 3

x1 = 2

x2 = 3

Slope, m = (3 - - 1)/((3 - 2) = 4/1 = 4

For line B,

y1 = 5

y2 = 1

x1 = - 2

x2 = 0

Slope, m = (1 - 5)/((0 - - 2) = - 4/2 = - 2

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
